Suzuki GSX-R 1000 Service Manual: Sds check

Suzuki GSX-R 1000 Service Manual / Engine / Engine general information and diagnosis / Diagnostic information and procedures / Sds check

Using sds, sample the data at the time of new and periodic vehicle inspections.

After saving the sampled data in the computer, file them by model and by user.

The periodically filed data help improve the accuracy of troubleshooting since they can indicate the condition of vehicle functions that has changed with time.

For example, when a vehicle is brought in for service but the troubleshooting of a failure is not easy, comparing the current data value to past filed data value at time of normal condition can allow the specific engine failure to be determined.

Also, in the case of a customer vehicle which is not periodically brought in for service with no past data value having been saved, if the data value of a good vehicle condition have been already saved as a master (std), comparison between the same models helps to facilitate the troubleshooting.

Remove the front seat. Refer to “exterior parts removal and installation” in section 9d .
Set up the sds tool. (Refer to the sds operation manual for further details.)

Special tool
: 09904–41010 (suzuki diagnostic
system set)
: 99565–01010–020 (cd-rom ver.20)

Note

before taking the sample of data, check and clear the past dtc.
A number of different data under a fixed condition as shown should be saved or filed as sample.

Sample

Data sampled from cold starting through warm-up

Suzuki GSX-R. Sample

Data at 3 000 r/min under no load

Data at the time of racing

Data of intake negative pressure during idling (100 °c)

Data of manifold absolute pressure operation at the time of starting

Example of trouble

Three data; value 3 (current data 3), value 1 (past data 1) and value 2 (past data 2); can be made in comparison by showing them in the graph. Read the change of value by comparing the current data to the past data that have been saved under the same condition, then you may determine how changes have occurred with the passing of time and identify what problem is currently occurring.

Note

with dtc not output, if the engine idling speed and isc valve stepping position are found to be abnormal than the data saved previously, the possible cause may probably lie in the hardware side such as isc valve air inlet hose crumple, bend, etc.
